Application ,filed May 16,

My invention relates to bobbins particu- -larly adaptable for supporting silk or other thread orlyarn which is to be steamed ordried. g 5 One important object of the invention is to construct the bobbin entirely of sheet metal parts secured and interlocked'to'gether to produce a strong and durable structure- Another important object is to prov de 1m-- 6 proved arrangement of openings and circulaa 'tory passages for permitting intimate and voluminous contact of steam, air-or heat with the bobbin contents so that the treatment can be rapidly and efficiently accomplished.

The above features, and other are incorporated in'the structure shown on the draw ings in which Y I Fig. l is a side elevation of the bobbin, V Fig. 2 is an end elevation of the bobbin,

' V Fig. 3 is aiplan View of an enddisk, I

edges joinedby the seam 14. As its ends the hub has the tongues 15 which extend through the openings-16in the end disks and are deflected radially-outwardly against the outer faces of-the disks and lock the disks to the hub ends.

with recesses 18. The spindle tube 131s formed of sheet metal and at its ends has tongues 19, the tube extendingbetween the end disks and the tongues engaging in the recesses'18 and projecting primarily a distance beyond the disks as shown at the bottom of Fig. 4. These projecting tongue ends are then deflected radially outwardly against the outer faces of the end disks as shownin Fig. 4, and in Fig; 2, and thus rivetthe end disks to the spindle tube. Any number of tongues may be used but I prefer to use two wide, diametrically opposite, tongues at each' end of the tube, as shown. 1 5 To strengthen and stiffen the end disks made which would come Each end disk has an axial opening 1 7 1929. Serial No. 363,648;

their peripheral sections are curledover to form rims or treads. 20, and the innersection of each disk between the openings lb and17 is deflected outwardly to form an annular I boss 21,:the outer faces of the boss and rim 5 being preferablyin a common plane so that the bobbins may more readily stand on end and be stacked. The rim and boss will also protect the. tongues 15 and 19 against wear 1 1 i and injury.

llhe' tongues l engage gainst the: outer edges of h p gs 16, the openingsbeing in greater part exposed to afford ample passageway for circulation into and through the interior of the barrel 10 of steam, air or heat with which the bobbin contents are to be subjected, and the barrel has the perforations 22 I of suflicient number and so spaced that the 'bobbin'contents will be well and uniformly exposed'for the application and flow therethrough of the steam, air orlheat, so that st'eaming'or drying can be quickly 'and'efficiently accomplished. V

The tongues 15 may be spot weldedo'r-soldered to theend disks, and inorder to prevent the bobbin contents from catching in the 1 V corners between-the hub and disks, 'such'corners are preferably filled with solderi I donot desire to be limited 'tothe exact structure shown as modifications may be within the scope? ofthe inVention. 3 i

I claim:

1. A bobbin of the .class described T prising. a sheet metal barrel having tongues 1 )7 at itsends, and end disks having each a 0m cular row of openings for receiving at their 'outer endsthe respective tongues, vsaia tongues being "bent radially outwardly against the outer faces ofcthe disks to lock [the disks to the barrel,the inner ends of said openings serving to connect the interior of the barrel with the outside, said barrel having perforations for exposing the bobbin con-. tents to the interiorof'the barrel. '95 2. A bobbin of the class described com prising a cylindrical sheet metal barrel having tongues at its ends, sheet metal end having openings through'which said tongues extend, said tongues being'deflected against 109 2 a mam;

the outer faces of said disks to lock the disks to the barrel, said openings being in greater part exposed to form passageways for the free flowof steam or air through the barrel, 7 j 5 said barrelhaving perforations for exposing the bobbin contents to'the interior of theb'a'i' 7 rel, and a spindle tube extending axially through said barrel and interlocked with said 16 i In Witness whereoflI hereunto subscribe 4 my name this 10th day of April, 1929.
